alguem pra me responder ??? e urgente!! pfv

Answer 1

a) (x+1) (x+1)= x2+x+x+1=x2+2x+1
b) (2x+10) (2x+10)=4x2+20x+20x+100=4x2+40x+100
c) (xy +1/3) (xy+1/3)=x2y2+ 1/3xy+1/3xy+1/9=x2y2+2-1/3xy+1/9
d) (x+5) (x+5)=x2+5x+5x+25=x2+10x+25
e) (X5+2x3) (X5+2x3)=X10+2x8+2x8+4x9=X10+4x8+4x9
f) (6+x) (6+x)=12+6x+6x+x2=12+12x+x2
g) (2x+xy) (2x+xy)=4x2+2x2y+2x2y+x2y2=4x2+4x2y2+x2y2
h) (x2+1) (x2+1)=x4+x2+x2+1=x8+1
i) (x+2y) (x+2y)=x2+2xy+2xy+4y2=x2+4xy+4y2
j) (x3+1/3) (x3+ 1/3)=x6+1/3x3+1/3x3+1/9=x6+2-1/3x+1/9
